Title: System and method for controlling flow rate of working oil
Inventor: LUNZMAN STEPHEN V
IPC: G05D7/06
Filed: 2002-12-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide device and method for controlling flow rate of working oil.  <P>SOLUTION: This method for controlling flow rate of working oil passing through a valve communicated with a pump and a hydraulic actuator is provided. The method includes monitoring of load pressure of the valve, and selecting of a flow rate limit and a pressure limit of the valve. A flow rate- pressure relation of the valve is determined based on the flow rate limit, the pressure limit and the desired flow rate-pressure characteristic. A working oil flow rate command is calculated based on the determined flow rate-pressure relation of the valve and the monitoring load pressure of the valve.  <P>COPYRIGHT: (C)2003,JPO

Patent JP-2004505775-A (JP)
IPC: B22D11/128
Filed: 2001-08-07
Abstract: A method and strand guide for supporting, guiding and cooling casting strands (1) made of steel, especially preliminary sections (2) for girders, which are cooled by injected water (29) and are drawn. The inventive method prevents cracks, especially surface cracks, from appearing in the microstructure by adapting the cooling conditions of the surface of the strand during secondary cooling. Undercooling of the chill of the strand is prevented by adapting the cooling and support of the beam blank format to the solidification range in order to avoid an undesirable solidification structure on the upper flange edges or in other cross-sectional areas so that cooling and support are provided exclusively where a crater is formed. The casting strand (1) is cooled by guiding the temperature in a specific manner in upper supporting segments (5, 6, 7) by means of injected water jets whose width at least matches the length of the supporting rollers on longitudinal and transversal sides (13, 14) of the cross section (1a) of the casting strand, and is decreasingly supported in an analogous manner with respect to the length of the casting path and the cooling state in core areas (15) of the cross section (1a) of the casting strand on the transversal sides (14) of said casting strand cross section (1a) and cooling occurs exclusively by means of water jets (8) which are oriented towards said core areas (15).
